ACUTE MYOCARDIAL INFARCTION;

HYPOMAGNESEMIA IN PATIENTS

Abstract

Objective: This descriptive case series study evaluates the frequency of
hypomagnesemia in patients with acute myocardial infarction. Patients and methods: This
multidisciplinary conducted at Liaquat University Hospital Hyderabad and a private hospital
Hyderabad from May 2010 to October 2010. All patients diagnosed as acute myocardial
infarction were further evaluated for type of myocardial infarction and serum magnesium level.
Results: Out of 100 diabetic patients, 77 were males and 23 patients were females. The mean
age and standard deviation of patients of male and female was 54.78 ± 8.82 (SD) and 53.64 ±
10.82 (SD), respectively. The mean ± SD for serum magnesium in overall subjects was 1.24
±0.48. Regarding the type of AMI inferior wall in 22 (29%), lateral wall in 17 (22%), anteroseptal in
12 (16%), anterolateral -V1 in 07(09%), right ventricular in 10 (13%) and posterior wall in 07 (09%).
The mean duration of acute MI in male and female population was 8.71±6.73 hours and
17.70±14.57 hours (p<0.01) where as the mean duration of acute MI in hypomagnesemic and
normomagnesemic patient was 5.16±2.49 hours and 26.60±8.27 (p = 0.02) respectively. The
mean serum magnesium level in male as well as female population was 1.32 ±0.21 mg/dl and
1.46± 0.53 mg/dl p = 0.05, respectively. Regarding the hypomagnesemia in male and female
population was 34(75.6%) and 16(53.3%) p=0.04, respectively. The hypomagnesemia was more
predominant in inferior 18(36.0%) and lateral 16 (32.0%) wall MI. Conclusions: The
hypomagnesemia was observed in patients with acute myocardial infarction with statistical
significance
